Wear and performance sling with hybrid material webbiing

Abstract

A webbing for use with a tiedown or sling which has overall increase strength efficiency when compared to known tiedowns or slings which use texturized yarn. The webbing contains non-texturized yarn material having reduced elongation characteristics in the core, combined with non-texturized yarn having higher elongation and improved wear characteristics on the exterior surfaces.

The invention claimed is: 
     
       1. A webbing tiedown or sling comprising:
 a woven webbing comprising:
 two primary exterior surfaces uniformly bound together through a central core; 
 the core having synthetic, first thermoplastic yarn material wherein at least 75% of the first thermoplastic yarn material is non-texturized and continuous filament; 
 the two primary exterior cover surfaces having second thermoplastic yarn material wherein at least 50% of warp of the second thermoplastic yarn material is non-texturized and continuous filament; 
 the warp of the second thermoplastic, non-textured yarn material of the two cover surfaces having good abrasion characteristics and also having higher elongation characteristics during tensioning than the first thermoplastic, non-textured yarn material, yielding an approximately 10% or higher elongation during tensioning than that of said first thermoplastic, non-textured yarn material. 
 
 
     
     
       2. The webbing tiedown or sling as recited in  claim 1 , wherein the first thermoplastic yarn material in the core is polyester. 
     
     
       3. The webbing tiedown or sling as recited in  claim 1 , wherein the second thermoplastic, non-textured yarn material in the cover surfaces is nylon. 
     
     
       4. The webbing tiedown or sling as recited in  claim 1 , wherein an appearance of the first thermoplastic yarn material in the core is different than an appearance of the second thermoplastic yarn material of the cover surfaces, wherein if the second thermoplastic yarn material of the cover surfaces is compromised, the appearance of the first thermoplastic yarn material in the core is used as an out of surface marker. 
     
     
       5. The webbing tiedown or sling as recited in  claim 1 , wherein at least 50% of the first thermoplastic yarn material is non-texturized and at least 50% of the second thermoplastic yarn material is non-texturized, friction between the first thermoplastic yarn material and the second thermoplastic yarn material is reduced compared to the friction that occurs between texturized materials, wherein as the second thermoplastic yarn material is moved or elongated at a different rate than the first thermoplastic yarn material, the reduced friction results in less heat being generated between the second thermoplastic yarn material and the first thermoplastic yarn material. 
     
     
       6. The webbing tiedown or sling as recited in  claim 1 , wherein high lubricity coating is applied to the first thermoplastic yarn material, the second thermoplastic yarn material, or both. 
     
     
       7. A tiedown or sling comprising:
 a woven webbing comprising; 
 a core having core material having reduced elongation characteristics in the core; and 
 a cover having cover material which is predominantly non-texturized having higher elongation than the core material and improved wear characteristics; 
 wherein at least 50% of the core material is non-texturized and at least 50% of the cover material is non-texturized, friction between the core material and the cover material is reduced compared to the friction that occurs between texturized materials, wherein as the cover material is moved or elongated at a different rate than the core material, the reduced friction results in less heat being generated between the cover material and the core material. 
 
     
     
       8. The tiedown or sling as recited in  claim 7 , wherein the core material is predominantly non-texturized yarn material. 
     
     
       9. The tiedown or sling as recited in  claim 7 , wherein the core material is polyester yarn. 
     
     
       10. The tiedown or sling as recited in  claim 9 , wherein the cover material is nylon yarn. 
     
     
       11. The tiedown or sling as recited in  claim 7 , wherein the core is enclosed and retained in an opening of the cover, the opening is provided between a top surface, a bottom surface and edge surfaces of the cover. 
     
     
       12. The tiedown or sling as recited in  claim 7 , wherein the core material is woven yarn material. 
     
     
       13. The tiedown or sling as recited in  claim 12 , wherein the cover material is woven yarn material. 
     
     
       14. The tiedown or sling as recited in  claim 7 , wherein an appearance of the core material is different than an appearance of the cover material, wherein if the cover material is compromised, the appearance of the core material is used as an out of surface marker. 
     
     
       15. A woven webbing comprising:
 predominantly a first non-texturized yarn material having reduced elongation characteristics in a core of the webbing; and 
 predominantly a second non-texturized yarn having higher elongation and improved wear characteristics on an exterior surface of the webbing; 
 wherein at least 50% of the first non-texturized yarn material is non-texturized and at least 50% of the second non-texturized yarn material is non-texturized, friction between the first non-texturized yarn material and the second non-texturized yarn material is reduced compared to the friction that occurs between texturized materials, wherein as the second non-texturized yarn material is moved or elongated at a different rate than the first non-texturized yarn material, the reduced friction results in less heat being generated between the second non-texturized yarn material and the first non-texturized yarn material. 
 
     
     
       16. The woven webbing as recited in  claim 15 , wherein the first non-texturized yarn material is woven yarn material. 
     
     
       17. The woven webbing as recited in  claim 15 , wherein the second non-texturized yarn is woven yarn material. 
     
     
       18. The woven webbing as recited in  claim 15 , wherein an appearance of the first non-texturized yarn material is different than an appearance of the second non-texturized yarn material, wherein if the first non-texturized yarn material is compromised, the appearance of the first non-texturized yarn material is used as an out of surface marker. 
     
     
       19. The woven webbing as recited in  claim 15 , wherein high lubricity coating is applied to the first non-texturized yarn material, the second non-texturized yarn material, or both. 
     
     
       20. The woven webbing as recited in  claim 15 , wherein during tensioning, the first non-texturized yarn material yielding an approximately 10% or higher elongation at break than the second non-texturized yarn material.
